Wave Function Collapse
Wave Function Collapse is a procedural content generation algorithm that uses an extension of constraint solving. For example, a cell’s possible values might be constrained by the cells adjacent to it, or there might be a global limit like only allowing one boss room and 2-4 treasure rooms per floor. This is not to be…

Influence Maps, Ants, and Flocking
An influence map is a grid-like data structure where each cell carries information about its surroundings. This is typically in terms of threat or safety, whether that be cover or line of sight on a target, squad cohesion or separation, range of potential attacks, or even emergency evasive action against incoming attacks. This makes it…

Flow Fields
Flow fields are a technique applicable when many units need to pathfind to the same location. It is an extension of traditional pathfinding algorithms, but instead of only calculating one path per unit it calculates a path for every cell on the grid, reusing information from other known paths. This has a high immediate cost,…

Platformer analysis: Generating graphs for pathfinding
Overview To create this algorithm, I first looked at how NavMeshes work. We can’t add all possible points on the mesh, since those are effectively infinite, so instead we simplify polygons into single nodes, and connect those that have a common edge. After processing this with our pathfinder, we can interpolate the details. Simplifying this…
